What is an umbilical hernia? An umbilical hernia is a bulge through the abdominal muscles in the area of the navel (belly button). The hernia may contain tissue from the abdomen, part of an organ (such as the intestine), or fluid.
Iliac crest contusion occurs due to bleeding of abdominal muscles and swelling. This can cause excruciating pain when the person tries to move his hip region. Bleeding can occur on the periosteum region of the bone resulting in inflammation and the muscles of the iliac crest would develop spasms.
Dr. Edward Hellman Dr. Hellman. 2 doctors agreed: Hard to say: The iliac bone is part of the pelvis and so if the lesion is painful, it would be expected to cause pelvic pain. If it is really large, it could potentially cause abdominal pain or sometimes there might be other lesions in other areas. A lot really hinges around the diagnosis of the lesion itself.
